For most Americans, healthcare is the single biggest worry about moving abroad. The good news: many popular destinations offer care that is good and far cheaper than in the U.S. The catch: the coverage you count on at home mostly stops at the border, and you have to build a new plan before you leave.
This guide explains the three layers you'll be working with: the local public system, private care, and the U.S. benefits that do (and don't) follow you overseas. If you're a veteran, read the VA section closely. Some benefits travel with you, and many veterans don't know it.
How public systems work for legal residents
Most countries run some form of public or social-insurance health system. As a tourist you generally can't join it. Once you hold legal residency, the door often opens, but each country sets its own terms. Some cover residents through general taxes, some require monthly contributions, and some make enrollment mandatory as a condition of keeping your residency.
A few examples show how wide the range is:
| Country | Public system | How residents typically access it |
|---|---|---|
| Portugal | SNS (Serviço Nacional de Saúde) | Legal residents can get an SNS user number. Portugal's government says coverage depends on linking that number to your ID, tax number (NIF), address and a valid residence permit. |
| Spain | National Health System, run by the regions | Workers paying into social security are covered. Economically inactive residents with no other route can buy into the convenio especial after one year of residence and municipal registration. Spain's Ministry of Health lists the fee as €60 a month under 65 and €157 a month at 65 and over. |
| Mexico | IMSS | People without other social security can buy IMSS family health coverage for an annual fee scaled by age. Some pre-existing conditions bar enrollment and others carry waiting periods. Confirm current eligibility for foreign residents at your local IMSS office. |
| Costa Rica | CCSS (the "Caja") | Most legal residents must enroll and pay a monthly contribution. Falling behind can cause problems with residency renewals, so treat it as a fixed cost of living there. |
| Panama | CSS (Caja de Seguro Social) | Built mainly around workers and their dependents who pay in. Most foreign retirees rely on private insurance and private hospitals. |
| Thailand | Public hospitals and national schemes for Thai citizens | Foreign residents usually use private hospitals or pay as patients at public ones. Long-stay retirement visas such as the O-A require private health insurance. |
Two lessons from that table. First, "free public healthcare" rarely means free and automatic for a newly arrived American. Second, public systems are often good but slower, with waits for specialists and elective procedures, and staff who may speak only the local language. That's why many expats keep private insurance even when they're entitled to public care.
Private care and paying out of pocket
In much of Latin America and Southeast Asia, expats lean on private hospitals and clinics. Prices are often a fraction of U.S. rates, and paying cash for routine visits is common. Many private hospitals in major cities have international patient desks and English-speaking staff.
Cash works fine for a checkup. It doesn't work for a heart attack, a cancer diagnosis or a serious car accident. Those are the events insurance is for. Most expats end up with one of three setups:
- Public system only, accepting waits and language barriers, with savings set aside for private care when needed.
- Public plus private, using the public system as a backstop and a local or international policy for faster access.
- Private insurance only, common in countries where foreigners can't join the public system or where the visa requires it.
Our guide to international health insurance explains how those policies are underwritten and what visa applications usually demand.
What Medicare does and doesn't cover overseas
This is the point most retirees get wrong. Medicare.gov is blunt: Medicare usually doesn't cover health care while you're outside the U.S. For Medicare's purposes, "the U.S." means the 50 states, D.C., Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa and the Northern Mariana Islands.
Medicare may pay for a foreign hospital only in narrow situations:
- You're in the U.S. when an emergency happens and a foreign hospital is closer than the nearest U.S. hospital that can treat you.
- You're traveling through Canada between Alaska and another state without unreasonable delay, and a Canadian hospital is closer.
- You live in the U.S. and a foreign hospital is closer to your home than the nearest U.S. hospital that can treat your condition.
None of those help someone who lives in Lisbon or Cuenca. Medicare drug plans also don't cover prescriptions bought outside the U.S. Medicare Advantage plans must follow the same basic rules, though some offer extra coverage abroad. Check your plan's documents rather than assuming.
Medigap's foreign travel emergency benefit
Several Medigap plans (C, D, F, G, M and N among those sold today) include a foreign travel emergency benefit. According to Medicare.gov, it pays 80% of billed charges for certain medically necessary emergency care after a $250 yearly deductible, up to a $50,000 lifetime maximum, and only if the emergency begins during the first 60 days of a trip.
That's a useful safety net for a two-week vacation. It is not a health plan for someone living abroad full-time. A single hospitalization can exhaust the lifetime limit.
The Part B decision
Many expat retirees debate whether to keep paying Medicare Part B premiums for care they can't use abroad. If you drop it and later re-enroll, Medicare.gov says you may owe a late penalty of 10% of the standard premium for each full 12-month period you could have had Part B, usually for as long as you have it. We walk through the trade-offs in our retiring abroad guide.
Veterans: the VA Foreign Medical Program and CHAMPVA
Many of our readers served. If you have a VA-rated service-connected disability, the VA Foreign Medical Program (FMP) may pay for medically necessary care you receive outside the U.S. for:
- Your VA-rated service-connected disability.
- A condition associated with and aggravating a service-connected disability. The VA's own example is depression linked to service-connected PTSD.
- Care that is part of the Veteran Readiness and Employment (VR&E) program.
You can use any licensed provider in the country where you live or travel. FMP does not cover care for conditions that aren't service-connected, so a veteran with a 30% rating for a knee still needs other coverage for everything else.
How to use FMP
- Download your FMP benefits letter. It lists your covered conditions and is available in the Letters section of your VA.gov account.
- Show it to your provider. Ask them to file the claim with VA so VA can pay them directly.
- File yourself if needed. If you paid out of pocket, submit VA Form 10-7959f-2 (FMP Claim Cover Sheet) with an itemized bill and proof of payment. The VA says claims must be filed within two years of the date of care or hospital discharge.
- Keep your bank details current. How VA pays you depends on the account it has on file.
The VA also notes it suspended many providers in Panama after a long-running fraud scheme. If you live there, confirm your provider's status before relying on FMP.
CHAMPVA for your family
If you're rated permanently and totally disabled, your spouse and eligible dependents may have CHAMPVA. The VA's CHAMPVA guide explains that for beneficiaries living overseas, CHAMPVA acts as primary payer because Medicare generally doesn't cover care abroad. It also says beneficiaries who are entitled to Medicare Part A must enroll in and keep Part B to stay eligible for CHAMPVA, even if they live overseas. Dropping Part B to save money could cost your spouse CHAMPVA coverage. Confirm your family's situation with CHAMPVA before deciding.
Prescriptions and medications
Medication is where small problems become big ones. Before you move:
- Check whether each of your medications is legal and available in your destination. Some common U.S. drugs, including certain ADHD medicines and strong painkillers, are restricted or banned in some countries. The country's embassy is the place to ask.
- Get the generic name of every drug. Brand names change from country to country.
- Bring a supply to cover your transition, in original pharmacy packaging, with a copy of the prescription and a letter from your doctor.
- Find a local doctor early so you can get new prescriptions before you run out.
In many countries, some drugs sold by prescription in the U.S. are available over the counter, and prices are often lower. Don't let easy access replace medical supervision for chronic conditions.
Building your healthcare plan: first steps
- Research the public system in your shortlist countries: who qualifies, when, and at what cost. Our destination guides cover each country.
- Price private insurance before you commit, especially if you're over 60 or have pre-existing conditions.
- Decide on Medicare with the penalty math in front of you.
- Veterans: download your FMP letter and confirm CHAMPVA rules for your family.
- Gather records: medical history, vaccination records and prescriptions, in English and, ideally, translated.
- Visit a hospital on your scouting trip so you know where to go before you need it.
Check before you act
Immigration rules, income minimums, fees, and tax law change, sometimes with little notice. This guide is general information, not legal, immigration, or tax advice.
- Confirm current requirements with the country's official immigration agency or the consulate that will handle your application.
- For US tax questions, use IRS.gov and a tax professional who works with Americans abroad.
- Get advice from a licensed local attorney before signing leases, buying property, or submitting residency paperwork.
Common questions
Does Medicare cover me if I live abroad?
Generally no. Medicare.gov says Medicare usually doesn't pay for care outside the U.S., with narrow exceptions such as certain emergencies near the U.S. border. Plan on local public coverage or private insurance where you live.
Can I use VA health care overseas?
Veterans with VA-rated service-connected conditions can use the VA Foreign Medical Program, which may pay for care of those conditions from licensed providers abroad. It does not cover non-service-connected care.
Can foreigners join public health systems abroad?
Many countries let legal residents join, either free, through taxes, or by paying a contribution. Portugal, Spain, Mexico and Costa Rica all have routes for residents, but the rules differ a lot. Tourists usually cannot enroll.
Should I keep Medicare Part B if I move abroad?
It's a personal decision with a real cost either way. Dropping Part B saves premiums, but re-enrolling later can trigger a permanent late penalty. See our retiring abroad guide for the trade-offs.
